Method of charging and distributing power between a plurality of rechargeable batteries

A method of charging and distributing power between a plurality of rechargeable batteries connected to a power management circuit, the method comprising:

• providing a battery charging circuit configured to be connected to at least two of the plurality of rechargeable batteries;
• supplying, via the battery charging circuit, a charging current to a first rechargeable battery of the plurality of rechargeable batteries;
• monitoring the first rechargeable battery while receiving the supplied charging current;
• detecting a charging fault in response to monitoring the first rechargeable battery receiving the supplied charging current;
• switching, in response to the detected charging fault of the first battery, the battery charging circuit to supply the charging current via to a second rechargeable battery of the plurality of rechargeable batteries;
• providing a battery discharge circuit configured to receive a stored rechargeable battery power from at least one of the plurality of rechargeable batteries;
• detecting a first user input to cause the at least one of the plurality of rechargeable batteries to discharge stored rechargeable battery power to an electrical load;
• and
• receiving a second input to cause the at least one of the plurality of rechargeable batteries to receive, via the battery charging circuit, the charging current.

A method of charging and distributing power between a plurality of rechargeable batteries connected to a power management circuit, the method comprising:

• supplying, via a battery charge and distribution circuit, a charging current to at least one of a plurality of rechargeable batteries;
• monitoring, via a monitoring circuit, the at least one of the plurality of rechargeable batteries and the battery charge and distribution circuit concurrently with supplying the charging current;
• and
• at least one of
• determining, by the monitoring circuit, a charging fault in the at least one of the plurality of rechargeable batteries, and based on determining the charging fault in the at least one of the plurality of rechargeable batteries, switching the battery charge and distribution circuit to supply the charging current to another one of the plurality of rechargeable batteries, and
• determining, by the monitoring circuit, a charging fault in the battery charge and distribution circuit, and based on determining the charging fault in the battery charge and distribution circuit, switching to another battery charge and distribution circuit to supply the charging current to the at least one of the plurality of rechargeable batteries.
